Z4 tablet battery

Hi,

My new xperia z4 battery life seems decreased quiet significantly and the screen usage is 85% is this normal? have a look at attached picture. That's only from non heavy use really. Watched a few YouTube videos. You got any tips. I also got xperia z2 tablet but it's at Sony for repairing the on button, but there the battery seemed better. Many thanks

Yes that's what I thought. Tablet had about 7-10 charges and new. Another thing is that the battery shows as charged from 0% to 100% in about 2 hours 40 minutes. I mean it seems like the tablet will have run out on juice in about 6h and its normal use. I never head this in my previous z2 tablet.

I had this tablet 2,5 weeks now.

After adjusted brightness the screen usage is about 50% however there are still the battery issues. Not even 5 h med to high usage. Will it qualify for warranty repair/checkup?

Hmm after the same usage on z2 tablet the battery goes down significantly slower. On z4 tablet 30-40% faster. Brightness levels are more high on z2 aswell.

I have stamina mode off and am using my tablet throughout the day, but admittedly not running videos all the time or games. I'm getting well over 1 day from a full charge, and it is better than the battery life in my old Z Tablet. What apps are you running on your tablet?

Hi,

sorry i wasnt here for a while. After speaking to support via Chat they advised me to repair my software through PC Companion - which i did. Now i have done this a few days ago and charged tablet about 3 times now - and unfortunatelly i only get still about 6h of usage. It's kind off a mixture from MX Player, All Player, 8 Ball Pool Miniclip, uTorrent and a bit of browsing. Same usage and the same apps had been tested on my old Xperia Z2 Tablet and i get just over 8 hours of usage. Could anybody comment on this. I still will do a bit of testing before i speak to support chat again. When i bought this Tablet the usage i got was far better over 10 hours.

Many Thanks

Heh I just been on the Sony support chat but they totally ignored me, therefore I will be sending this off to the carrier directly...
